Python
Default modes
There are a number of python modes for Emacs. fgallina's python.el is the python.el included in Emacs 24.2 and onwards.
External extensions
rope & ropemacs
rope is a library for refactoring and manipulating Python code. ropemacs is an Emacs interface to the rope library.
Flymake
flymake is a on-the-fly syntax checker for Emacs. We can use it alongside with flyspell.
To run pep8, pylint, pyflakes and unit-tests (with nose), you can be interested in using flymake-python.
Pymacs
Pymacs is an Emacs extension that enables the use of Python alongside with Emacs Lisp.
emacs-for-python
emacs-for-python is a bundle of the above modes (and more), and it's an easy way to turn Emacs into a Python IDE.
Ipdb, ipython debugger
If you call ipdb, the execution will stop and give a nice ipython-looking prompt. Just add `import ipdb; ipdb.set_trace()`
You can use the following to highlight this line, and not forget it :
; Highlight the call to ipdb
; src http://pedrokroger.com/2010/07/configuring-emacs-as-a-python-ide-2/
(defun annotate-pdb ()
(interactive)
(highlight-lines-matching-regexp "import ipdb")
(highlight-lines-matching-regexp "ipdb.set_trace()"))
(add-hook 'python-mode-hook 'annotate-pdb)
pdb track
If you use emacs-for-python given above, you can track your source code while debugging with pdbtrack.
A tool to use in a non-emacs terminal would be pdbpp
